Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed October 2 1, 1904. Serial No. 229,789.

To (bi/Z whom it may concern;

Be it known that I, JOHN R. MITCHELL, a citizen of the. United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and usefullmprovement in Coupler CenteringDevices andCarry- Irons for Railway-Cars, of which the following is aspecification.

My invention relates to improvements in centering devices and stirrupsor carry-irons for railway-car couplers.

The object of my invention is to provide a coupler centering device andcarry-iron of a simple, efficient, strong, and durable constructionwhich will properly support the coupler and permit it to have thenecessary swinging or lateral movement in passing around curves and atthe same time hold the coupler normally in its proper central positionin respect to the car.

My invention consists in the novel construction of parts and devices andin the novel combinations of parts and devices herein shown anddescribed and by which this object or result is accomplished.

In the accompanying drawings, forming a part of this specification,Figure l is a side elevation, partly in longitudinal vertical section.of a passengencar coupler embodying my invention. Fig. 2 is a verticalcross-section on the broken line 2 2 of Fig. 1, showing the couplercentering device and carry-iron in elevation. Fig. 3 is a verticalcentral crossscction through the centering device. Fig. I is a verticalsection on line 4 L of Fig. 3. Fig. 5 is a horizontal section on line 55 of Fig. 3, and Fig. 6 is a vertical section on line 6 6 of Fig. 3.

In the drawings, A represents a portion of the oar-frame; A, thecoupler; A the drawbar; A", the draftrigging spring; A, the buffer; A,the buffer-spring, these parts being of any ordinary or customaryconstruction.

B is the coupler carry-iron, the same being preferably of the usual orcustomary form and secured to the car-frame by bolts Z) 6 in the usualmanner. The coupler centering device comprises atransversely-reciprocating saddle I), having upwar dly-projecting guidewings or lugs (Z, which fit and reciprocate on each side of thecarry-iron B and which are furnished with shoulders (Z, fitting on eachside of the coupler draw-bar A a pair of stops or angle-plates F F,bolted to the carryiron, a spring G, a pair of followers H H, and a boltor guide-stem K, secured to the stops and extending through the spring.

' The spring abuts at each end against the fol lowers, and each followeris adapted to engage the stops and also the transversely-reciprocatingsaddle D, so that when the drawbar swings or moves to either side thespring will be compressed, thus causing the spring to return thedraw-bar to its central position. The followers H H are preferablyprovided with integral thimble portions 71. to guide the spring. Thetransversely-reciprocating saddle D is preferably of malleable iron orother cast metal and is furnished with an upper integral web (Z whichfits beneath the carryiron B, and with a lower integral web (Z below thespring Or. The spring G isthus embraced and inclosed between thetransverselyreciprocating saddle D and the carry-iron B. Thetransversely-reciprocating saddle D of the centering device has integralshoulders (V to engage the followers.

In my invention the coupler draw-bar is supported by the carry-iron B inthe usual manner, and the transversely-reelprocating saddle is mountedbeneath the carry-iron and supported therefrom through the connectingbrackets or angle plates F F, which serve also as stops for thefollowers to abut against.

The saddle D is supported from the brackets F through theconnecting-bolt K and followers H, the saddle resting directly upon thefollowers and the followers resting upon the connecting-bolt K. Mycentering-saddle is thus entirely relieved from the weight of thedraw-bar and from any binding strains to which the draw-bar may besubjected from the cars coupled thereto.

I claim 1. The combination with a coupler drawbar and a carry-ironsupporting the same and upon which the draw-bar rests, of a centeringdevice for the draw-bar, comprising a transversely-reciprocating saddlefitting under the carry-iron and having upwardly-projecting wingsfitting on each side of the carry-iron, and furnished with shouldersengaging the draw-bar, and having also shoulders to engage a pair offollowers, a pair of stops or angle-plates secured to the carry-iron, apair of followers adapted to abut against said stops and to engage saidshoulders and said transversely-reciprocating saddle, a spring betweensaid followers and a supporting pin or bolt extending through saidspring, followers, stops and saddle, the carry-iron fitting between thedraw-bar and said saddle and leaving the saddle free from the weight ofthe draw-bar, substantially as specified.

free from the weight of the draw-bar, substantially as follows.

3. The combination with a coupler drawbar and carry-iron upon which thedraw-bar rests, of a pair of stops or angle-plates secured to saidcarry-iron, a pair of followers between said stops, a spring betweensaid followers and a transversely-reciprocating saddle fitting under thecarry-iron and having upwardly projecting wings engaging the draw-bar,and shoulders to engage the followers, and a connecting-bolt extendingthrough said saddle and said stops or angle-plates, the carry ironrelieving the saddle from the weight of the draw-bar and the carry-ironbeing furnished with a lower integral web (Z below the spring andinclosing the same, substantially as specified.
